세탁기의 액체세제 공급방법{METHOD FOR INJECTING LIQUID DETERGENT IN A WASHING MACHINE}Liquid detergent supply method of washing machine {METHOD FOR INJECTING LIQUID DETERGENT IN A WASHING MACHINE}

본 발명은 세탁기의 액체세제 공급방법에 관한 것으로, 더욱 상세하게는 액체세제의 부족을 알리는 에러메시지가 표시된 후에도 일정횟수 세탁행정이 수행되도록 할 수 있는 세탁기의 액체세제 공급방법에 관한 것이다.The present invention relates to a liquid detergent supplying method of a washing machine, and more particularly, to a liquid detergent supplying method of a washing machine capable of performing a predetermined number of washing cycles even after an error message indicating a lack of liquid detergent is displayed.

일반적으로 세탁기는 세제의 유화작용과 펄세이터의 회전에 따른 수류의 마찰작용 및 펄세이터가 세탁물에 가하는 충격작용 등을 이용하여 의복, 침구 등에 부착된 각종 오염물질을 제거하는 제품으로, 최근에 등장하는 전자동 세탁기는 중간에 사용자의 조작 없이 세탁, 헹굼, 탈수로 이어지는 일련의 과정을 자동으로 진행한다.Generally, a washing machine is a product that removes various contaminants attached to clothes and bedding by using emulsification of detergent, friction action of water flow due to rotation of pulsator, and impact action of pulsator on laundry. Fully automatic washing machine automatically proceeds a series of processes leading to washing, rinsing, and dehydration without user intervention.

이러한 세탁기는 세탁물이 수용되는 세탁조의 형태에 따라 상기 세탁조가 세워져 있는 탑로딩(Top-loading) 방식 세탁기와 세탁조가 누워있는 드럼(Drum) 방식 세탁기로 대별할 수 있다. 이 중에서도 드럼 세탁기는 탑로딩 세탁기에 비해 전체 높이를 줄일 수 있을 뿐만 아니라, 세탁용량을 늘릴 수 있고 포꼬임 등의 문제가 거의 발생되지 않으므로 그 수요가 점점 더 늘어나고 있는 추세에 있다.Such a washing machine may be roughly classified into a top-loading washing machine in which the washing tank is standing and a drum washing machine in which the washing tank is laid, depending on the type of the washing tank in which the laundry is accommodated. Among them, the drum washing machine can not only reduce the overall height than the top-loading washing machine, but also can increase the washing capacity and hardly cause problems such as poking. Therefore, the demand for the washing machine is increasing.

종래의 드럼 세탁기는 세탁을 수행하기 전 세제통에 분말로 된 세제와 표백제 및 섬유유연제 등을 투입한 후, 컨트롤 패널을 통해 세탁물의 종류나 세탁시간 등을 설정하여 시작버튼을 눌러주면 세탁에서 헹굼 및 탈수에 이르는 일련의 과정을 자동으로 진행한다.In the conventional drum washing machine, after washing powder, detergent, bleach and fabric softener into the detergent container before washing, the type of laundry or the washing time are set through the control panel and the start button is pressed. A series of processes leading to dehydration are automatic.

한편, 최근에는 세탁수에 희석이 잘 되며 유화작용이 뛰어난 액체세제가 널 리 보급되고 있다. 이러한 액체세제를 세탁기에 투입하고자 할 경우, 드럼 세탁기의 특성상 세탁수가 공급된 상태에서 측면에 마련된 도어를 개방하여 세제를 투입하는 것이 불가능하기 때문에, 세탁수가 공급되기 전 세탁물에 직접 투입하든지 아니면 세제통을 통해 투입하여야만 한다.On the other hand, liquid detergents that are well diluted in washing water and excellent in emulsification have recently been widely spread. When the liquid detergent is to be put into the washing machine, it is impossible to inject the detergent by opening the door provided at the side in the state where the washing water is supplied due to the characteristics of the drum washing machine. It must be injected through.

이를 보안하기 위하여 분말세제를 투입하기 위한 분말세제통과 액체세제를 투입하기 위한 액체세제통이 각각 마련된 세탁기가 보급되고는 있으나, 이러한 종래의 세탁기는 액체세제를 이용하여 세탁행정을 수행하는 과정에서 액체세제가 완전하게 소비되면 세탁수를 급수하는 과정에서 급수관과 연통되어 있는 액체세제 공급관을 통해 세탁수가 유입된다. 이로 인하여, 액체세제통에 세탁수가 채워짐으로써, 세탁행정을 수행하는 과정에서 액체세제가 공급되지 않은 채 세탁이 진행되는 문제점이 발생하게 된다.In order to secure this, a washing machine provided with a powder detergent container for dispensing powder detergent and a liquid detergent container for dispensing liquid detergent has been widespread, but such a conventional washing machine is a liquid detergent in a process of performing a laundry administration using liquid detergent.

Washing water supply amount and the liquid detergent supply amount according to this embodiment is preferably calculated as the level of the wash water corresponding to the weight of the laundry.

이후, 급수량 및 액체세제 투입량이 산출되면(S20), 액체세제 투입과정(S100)을 수행한다.Then, when the water supply amount and the liquid detergent input amount is calculated (S20), the liquid detergent input process (S100) is performed.

먼저, 수용탱크(151) 내부의 액체세제 수위를 감지센서(157)가 감지하여(S110) 제어부(170)로 감지신호를 발생하면, 제어부(170)는 감지센서(157)에서 입력되는 감지신호에 따라 액체세제의 수위가 일정수위 이하인가를 판단한다(S111).First, when the detection sensor 157 detects the liquid detergent level in the receiving tank 151 (S110) and generates a detection signal to the control unit 170, the control unit 170 receives a detection signal input from the detection sensor 157. It is determined whether the level of the liquid detergent is below the predetermined level according to (S111).

판단결과(S111) 액체세제의 수위가 일정수위 이하로 내려가게 되면 제어부(170)는 액체세제의 부족을 알리는 액체세제의 부족을 알리는 에러메시지를 컨트롤 패널(111)에 표시한다(S120).As a result of the determination (S111), when the level of the liquid detergent drops below the predetermined level, the controller 170 displays an error message indicating the lack of the liquid detergent to the control panel 111 (S120).

그리고 컨트롤 패널(111)에 에러메시지가 표시(S120)된 후에도 수용탱크(151)에 잔존하는 액체세제를 이용하여 세탁행정을 더 수행할 수 있도록 세탁횟수가 일정횟수 예를 들어 3회 이하인지를 판단하여(S121), 세탁횟수가 3회 이하이 면 세탁횟수를 카운터하여 증가시킨다(S130). 이때, 컨트롤 패널(111)에 액체세제의 부족을 알리는 에러메시지가 표시된 후(S111), 세탁행정을 수행하여 세탁횟수가 3회를 초과하게 되면(S121), 세탁행정을 중단하고 에러메시지를 지속적으로 표시한다(S120).After the error message is displayed on the control panel 111 (S120), whether the number of washings is a certain number of times, for example, three times or less, so that the washing operation can be further performed using the liquid detergent remaining in the receiving tank 151. If it is determined (S121), if the washing count is less than three times, the washing count is counted and increased (S130). At this time, after the error message indicating the lack of liquid detergent is displayed on the control panel 111 (S111), if the washing cycle exceeds three times (S121), the washing cycle stops and continues the error message It is displayed as (S120).

세탁횟수가 카운팅되면(S130), 제어부(170)의 제어에 따라 세제밸브(155a) 및 급수밸브(135)가 개방된다(S140).When the washing count is counted (S130), the detergent valve 155a and the water supply valve 135 are opened (S140) under the control of the controller 170.

이후, 세제밸브(155a) 및 급수밸브(135)의 개방(S140)에 따라 급수관(130)을 통해 세탁수가 유입되면서 액체세제가 급수관(130)으로 유입되면 제어부(170)는 급수에 따른 액체세제 공급시간을 카운팅하여(S150) 액체세제의 투입량에 따른 시간이 경과되었는가를 판단한다(S151). 본 실시예에 따른 액체세제의 공급시간은 세탁물의 중량에 대응되는 세탁수의 수위로서 산출되는 것이 바람직하다.Subsequently, when the wash water flows through the water supply pipe 130 according to the opening of the detergent valve 155a and the water supply valve 135, and the liquid detergent flows into the water supply pipe 130, the control unit 170 controls the liquid detergent according to the water supply. The supply time is counted (S150) to determine whether the time according to the input amount of the liquid detergent has elapsed (S151). The supply time of the liquid detergent according to this embodiment is preferably calculated as the level of the wash water corresponding to the weight of the laundry.

판단결과(S151) 액체세제 투입시간이 경과되면 제어부(170)의 제어에 따라 개방되어 있던 세제밸브(155a)를 차단하여 액체세제의 공급을 중단한다(S160). 또는 판단결과(S151) 액체세제 투입시간이 경과되지 않으면 액체세제 공급시간을 카운팅하는 단계(S150)를 계속 수행한다.As a result of the determination (S151), when the liquid detergent input time has elapsed, the detergent valve 155a opened under the control of the controller 170 is blocked to stop the supply of the liquid detergent (S160). Alternatively, if the determination result (S151) does not pass the liquid detergent input time, the step of counting the liquid detergent supply time (S150) continues.

계속하여, 세제밸브가 차단(S160)된 상태에서도 급수밸브(135)가 개방되어 있으므로, 세탁수는 계속하여 공급되는데, 이때, 제어부(170)는 터브(120) 내로 공급되는 세탁수의 수위를 감지하여(S30), 세탁수의 수위가 세탁물의 중량에 따른 급수량에 도달하였는가를 판단한다(S31). 세탁수의 수위 판단결과(S31), 세탁수의 수위가 세탁물의 중량에 따른 급수량에 도달하면 급수밸브(135)를 차단하고(S40), 세 탁을 시작한다(S50).Subsequently, since the water supply valve 135 is opened even in the state in which the detergent valve is blocked (S160), the washing water is continuously supplied. At this time, the controller 170 controls the level of the washing water supplied into the tub 120. By sensing (S30), it is determined whether the water level of the wash water reaches the water supply amount according to the weight of the laundry (S31). When the water level determination result of the washing water (S31), when the water level of the washing water reaches the water supply amount according to the weight of the laundry, the water supply valve 135 is blocked (S40), and washing is started (S50).

한편, 액체세제의 수위가 일정수위 이하인가를 판단한 결과(S111), 액체세제의 수위가 일정수위를 초과하게 되면, 세탁횟수 카운트 단계(S130)에서 카운팅된 세탁횟수 카운트를 초기화 하고(S113), 세제밸브(155a) 및 급수밸브를 개방하는 단계(S140)를 수행한다.  On the other hand, as a result of determining whether the level of the liquid detergent is below a certain level (S111), when the level of the liquid detergent exceeds a certain level, the washing count count counted in the washing count count step (S130) (S113), The detergent valve 155a and the water supply valve are opened (S140).

본 실시예에서는 액체세제의 부족에 따라 에러메시지가 표시된 후(S20), 세탁행정을 수행하는 세탁횟수가 3회인 것을 예를 들어 설명하고 있지만, 세탁횟수를 2회 또는 4회 이상이 되도록 설정할 수도 있다. In this embodiment, after the error message is displayed due to the lack of liquid detergent (S20), for example, it is described that the washing cycle to perform the washing cycle three times, but the washing frequency may be set to be two or four times or more. have.
